Comments

• See propeller blades for assembly instructions.

• Sailplanes have no landing gear, and therefore would break a rigid propeller when the plane came in for a landing. The folding propeller folds back upon landing.

• The use of this hub will shorten the overall diameter of the prop by 10mm from the manufacturer's length listing.
